Spatial Memory Streaming with Rotated Patterns
We submit for evaluation an implementation of Spatial Memory Streaming (SMS), originally presented at ISCA 2006 by Somogyi, et al. Research has shown that memory accesses often exhibit repetitive layouts that span large memory regions (e.g., several kB), and that these accesses recur in patterns that are predictable through code-based correlation. SMS is a practical onchip hardware technique th...
متن کاملStreaming, Memory-Limited PCA
In this paper, we consider a streaming one-pass-over-the-data model for Principal Component Analysis (PCA). The input, in this case, is a stream of p-dimensional vectors, and the output is a collection of k, p-dimensional principal components that span the best approximating subspace. Consequently, the minimum memory requirement for such problems is O(kp). Yet the standard PCA algorithm require...
متن کاملTemporal Memory Streaming
While device scaling has led to continued processor performance improvement, scaling trends in DRAM technology have favored improving density over access latency. As a result, processors in modern servers spend much of execution time stalled on long-latency memory accesses. The conventional approach to latency tolerance—enlarging the on-chip cache hierarchy as transistor budgets scale—is provid...
متن کاملMemory Limited, Streaming PCA
We consider streaming, one-pass principal component analysis (PCA), in the highdimensional regime, with limited memory. Here, p-dimensional samples are presented sequentially, and the goal is to produce the k-dimensional subspace that best approximates these points. Standard algorithms require O(p2) memory; meanwhile no algorithm can do better than O(kp) memory, since this is what the output it...
متن کاملComputer Organization with Streaming Memory
Disks and drums are not really random-access devices.. A new device is -proposed, combining each disk or drum track with integrated circuit or core memory buffers, which yields a sector-wide random-access 'LWindowU into the track contents. The sequential nature of the device is acknowledged in providing for a forced swapping algorithm. Three potential applications are described. In a small mult...
